EA82 efi AFM terminology
Posted: Thu Jul 05, 2007 10:37 am
wiring connections on three plug ecu flap style afm has terms US, UFIX and UB and GROUND. I understand GROUND, what is the rest ? resitance type ???
This is only a guess
There has to be a power supply, so i assume UB
(sometimes the positive supply is called B+)
There must be a signal, so US
UFIX may be either for self calibration or even an air temp sensor?
